WikiPatroller was an Android app for identifying and reverting vandalism on Wikipedia. It used to be available for free on Google Play.

Please direct all questions, bug reports, and feature requests to the talk page.

WikiPatroller was available for free from the Google Play store, so it should've be quite easy to install. It required at least Android 3.0 (Honeycomb), and worked well on both phones and tablets. The app was advertisement-free.

The app required the rollback right (request it here). Other than this, there was no approval process.

Once logged in, the app showed a stream of recent changes from whichever wiki you chose (en.wikipedia.org by default). For each change, it displayed the name of the article, the user, the time, the number of characters added or removed, and most importantly, a diff of the edit in question. If you saw a disruptive edit, you could choose to either Revert, and provide an edit summary explaining why, or Revert vandal, and use the default edit summary. The Next button showed the next edit.

There was limited filtering capability: the app could show either all edits, or only those made by anonymous IP users.

Although designed for (and only tested on) on the English Wikipedia, WikiPatroller should have worked on all sites running MediaWiki software, including wikis in other languages.
